What is a sound wave?
A sound wave is a wave of compression and rarefaction by which sound is
propagated in an elastic medium such as air.
How do our ears absorb soundwaves?
Our ears are naturally designed to collect, focus, and transmit sounds
through a tiny and efficient conveyance system called the auditory pathway.
How does an echo work?
Echos are reflected sound.
This means that sound bounces off solid matter.
Sound reflected back to its source is an echo.
Why doesn't sound travel in a vacuum?
There are no atoms to vibrate to carry the sound waves.
It needs a medium to travel through.
What is it that determines the pitch of a note?
The pitch is determined by the sounds frequency.
If a sound increases, which wave characteristic is it likely increasing?
Amplitude is the only characteristic increasing.
